[amsat-bb] Beacon Rate on ISS

["Frank H. Bauer" <ka3hdo@xxxxxxxxxxx>]

Emily,

If someone is going to beacon, the recommendation is every 2 minutes.  This 
will provide 4-5 opportunities during a pass for the individual to get 
their packet through.

Actually, we discourage beaconing and autonomous operations with the 
ISS.  Automatic operations tends to fill our precious uplink frequencies 
with hundreds of packets, many times to satellites or an ISS that is not 
there.  And because there are so many people out there that want to 
communicate through ISS, beaconing can be considered interference.

Unless there is some kind of experiment going on (that I am not aware of) 
then a 15 second beacon does sound excessive.

Frank
